Overview
This mod bridges parts of Alex's Caves (the unofficial 1.21.1 port) with Create Nuclear.
Requirements
This mod requires BOTH of the following:
- Create
- Create Nuclear
You also need ONE of the two Alex's Caves 1.21.1 ports (do NOT install both):
- Alex's Caves Up (PixellCubed) — https://www.curseforge.com/minecraft/mc-mods/alexs-caves-up
- Alex's Caves Neo (TysonTheEmber) — https://www.curseforge.com/minecraft/mc-mods/alexs-caves-neo
Bridging Features
- Radiation is unified: Create Nuclear's radiation effect is replaced by Alex's Caves' irradiated effect.
- Radrock Uranium Ore in the Toxic Caves now drops Create Nuclear's Raw Uranium.
- The Toxic Caves now rarely generate the "Abandoned Reactor" structure (a small Create Nuclear reactor), with 4 variants of different damage levels, each containing 2 Rusty Barrel loot chests.
- Toxic Caves ruins chests can now contain Reactor Blueprints.
- The Toxic Caves now generate Radrock Iron Ore, Radrock Coal Ore, Radrock Lead Ore and Radrock Nitrate Ore.
- The Abyssal Chasm now generates Tuff Thorium Ore and Abyssal Thorium Ore.
- The Forlorn Hollows now generates Guanostone Nitrate Ore and Coprolith Lead Ore.
- Alex's Caves' Uranium, Uranium Shard, Uranium Rod and Block of Uranium are replaced in recipes and drops by Create Nuclear's Raw Uranium, Uranium Powder, Uranium Rod and Raw Uranium Block respectively.
- Alex's Caves' Uranium Rod is renamed "Uranium Candle" and is now purely decorative, crafted from Iron Ingot + Uranium Rod (Create Nuclear) + Iron Ingot.
- When Alex's Caves' Nuclear Bomb explodes, the blast area is converted into an irradiated biome just like a Create Nuclear reactor explosion, and can be cleared the same way.
- Alex's Caves' Nuclear Siren and Siren Light can now detect an impending reactor meltdown.
- Create Nuclear's Uranium Rod and Thorium Rod now work as Nuclear Furnace fuel: a Uranium Rod burns for roughly 512 items, a Thorium Rod for roughly 128 items.
- Create Nuclear's Anti Radiation armor now matches Alex's Caves' Hazmat suit: wearing it grants immunity to radiation, irradiated and acid damage, and the Anti Radiation suit no longer loses durability in acid.
- Create Nuclear reactor explosions can now hatch Tremorzilla Eggs.
Additional Tweaks
- The Nuclear Furnace smelts twice as fast as before.
- The Nuclear Furnace, Metal Barrel, Rusty Barrel, Gingerbarrel and Abyssal Altar are now compatible with Create's Funnels, Chutes and other automation devices.
- The Nuclear Furnace, Magnetic Quarry and Submarine now have Create-style Ponder tutorials; hold the corresponding item and press W to view them.
- The Abyssal Altar can be targeted by a Mechanical Arm, which can insert and extract items to automate Deep One trading.
- Muck in the Abyssal Chasm can now be smelted into Sea Glass Shards in a Furnace or Blast Furnace.
- Cats and Ocelots turn into Raycats after being continuously irradiated.
- Tremorzilla is immune to Create Nuclear reactor explosions and their knockback, so newly hatched Tremorzillas are not killed instantly.
- Create Nuclear's Thorium Rod and Uranium Rod can be used as Blaze Burner fuel, providing 80 seconds and 320 seconds of superheating respectively.
- Create Nuclear's Reactor Alarm now emits a redstone signal when the reactor goes critical, making automation easier.
